Rise in Zika Cases in Singapore

I never expect a spike in zika cases in Singapore. Till date, Singapore now has 56 people with zika virus. For now, I'll avoid Aljunied Crescent and Sims Drive are as many zika cases are diagnosed from these two places. Though they stated it's locally transmitted disease, I suspect it started when a man who returned from overseas was first infected with Zika virus. Perhaps they should never organise Olympics in Brazil. I reckon there be a spike in zika virus spread around the world soon.
